 already settled in `voice-bank-leading-region.md` (generic line, correct
 binding) and my first write-up wrongly reopened it; the other five languages; and play order, since the tool prints

+* **`MSG_DEMO_500`** — one page, KATANA, 2 s, **no text and no cue**. A
+  placeholder, apparently.
 * **Slot 2 is `None` at all 149 records**, so what it would hold otherwise is
   unknown — a constant with no observed variation carries no information.
-* **5 ids have more than one record** (`MSG_DEMO_600`–`604`), accounting for
-  the 11 extra records over 138 ids. Whether these are context variants or
-  duplicates was not investigated.

 * **Nothing here was run.** This is a static read of the tables; the playback
   order, and whether slot 3 is really the on-screen duration rather than an
   audio length or a delay, has not been checked against the running game.

+## ✅ The cue-less pages are the resupply lines — and they corroborate the movie work
+
+**Settled 2026-08-26.** 16 of the 17 pages with an empty slot 4 belong to five
+ids, and those five are exactly the resupply lines already documented from the
+*movie* side in [voice-bank-leading-region.md](../voice-bank-leading-region.md).
+The caption text matches word for word:
+
+| id | speaker | line | bank |
+|---|---|---|---|
+| `MSG_DEMO_600` | NATALIE | "Rhino 3 has landed. Commencing resupply." | `VOICE_D_450` |
+| `MSG_DEMO_601` | NATALIE | "Rhino Leader has landed. Commencing resupply." | `VOICE_D_451` |
+| `MSG_DEMO_602` | NATALIE | "Resupply complete. You are cleared for take-off!" | `VOICE_D_452` |
+| `MSG_DEMO_603` | TCAFSUPPLY | "All right, beginning resupply." | `VOICE_D_453` |
+| `MSG_DEMO_604` | TCAFSUPPLY | "Resupply complete. Switching to take-off sequence." | `VOICE_D_454` |
+
+This also explains the duplicate records. Each of these ids appears **once per
+stage that uses it**, and the repeat counts equal the movie-slot counts recorded
+independently for the corresponding banks — **5 of 5**:
+
+    DEMO_600 x3   DEMO_601 x3   DEMO_602 x4   DEMO_603 x4   DEMO_604 x2
+    D_450    x3   D_451    x3   D_452    x4   D_453    x4   D_454    x2
+
+Two facts fall out:
+
+* the **11 extra records over 138 ids** are these repeats, not an anomaly; and
+* slot 4 is empty on purpose — a resupply line's audio is bound through the
+  **movie** path (`VOICE_D_45x`), not through the `DEMO_nnn` cue path, so there
+  is no cue to name.
+
+The agreement is worth something beyond closing two items: the cutscene message
+table and the movie subtitle chain were decoded separately, from different
+containers, and they land on the same five lines with the same multiplicities.
